Image encryption based on chaotic tent map in time and frequency domains
The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...
متن کاملCryptanalysis of Image Encryption Scheme Based on Chaotic Tent Map
With the development of chaos theory, many image encryption algorithmshave been designed using the properties associated withthechaotic map. The chaotic map shows high sensitivity to initial conditions and the sequence generated using chaotic map are unpredictable making it a good choice for performing encryption operation. But, without proper encryption algorithm design, encryption scheme desi...
متن کاملAn Efficient Medical Image Cryptosystem Based on Chaotic Maps
With the growing applications of digital images in medical health system and the development of computer networks, medical image encryption has become an important technology to protect patients’ privacy when it is transmitted over open networks. Recently, chaos-based encryption approaches have been proven to be more effective for image encryption than other traditional methods (e.g. IDEA and A...
متن کاملChaotic Hybrid Bacterial Colony Chemotaxis Algorithm Based on Tent Map
Aiming at improving the global convergence speed of bacterial colony chemotaxis (BCC) optimization algorithm, a new chaotic hybrid bacterial colony chemotaxis (CHBCC) algorithm is introduced through the technique of hybrid algorithm. By integrating elitist strategy and chaotic optimization into bacterial colony chemotaxis optimization algorithm, it greatly enhances the local searching efficienc...
متن کاملComments on an image encryption scheme based on a chaotic Tent map
Recently an image encryption scheme based on a chaotic Tent map has been proposed by Li et al. [1]. This comment shows that this scheme is broken and no secure application can be found for it. The recent paper by Li et al. [1] proposed a chaotic image encryption based on a Tent map and evaluated its security through statistical analyses. It is true that when an image encryption scheme is design...
